Yep, i'd check the valve lash next, give us the engine model number and we can get the proper specification for you. Or something else is throwing off ignition timing
Maybe it is upside down. Will flip it around and see what happens.Stupid question, is it possible that the coil is mounted upside down? Most Briggs engines have the kill wire termial on the bottom. You did state you replaced the coil. May be wrong, it happened once before I think.
Yea, i see that the cotrol arm on front butterfly has an unused hole. If a spring was installed there, it would open after being choked/ closed. As it is it doesnt reopen. I could find some spring easy enough but theres no fixed anchor point for the spring.Coil air gap should be .010”. Most DYI use a business card to set, which does work. Push the throttle control all the way to choke the engine, the front butterfly should be closed. Pull back the control to high speed and that butterfly should open. Let me know what happens.
